Which one has the metallic tang?

[FellaAndrene]

long rant short...which cut of "Kush" would have that metallic smell/taste in it?

I've found it in Hindu Kush, the original, from Sensi Seeds. Also sold as "Afghan Kush" (by other seedbanks) and what not.

Purpotedly, it was a line made by Nevil: Jim Ortega's Kush 4 crossed with the Northern Lights #2.

According to Origins TK, a Hindu Kush plant was the father to OG Kush and Triangle Kush.

I remember reading that some Pure Kush cuts have that metallic twinge too.
